Aim: To evaluate the efficacy of 5.25% Sodium hypochlorite, UV rays for disinfecting Polyether Monophase and Polyvinyl monophase impression material. Materials and Methods: Ten healthy dentulous subjects irrespective of gender were selected. For each dentulous subject four impressions of maxillary arch were made with Polyvinyl siloxane and Polyether monophase impression material. First impression was kept as control. Second impression was disinfected with 5.25% sodium hypochlorite for 10 minutes. Third impression was disinfected by exposing it to UV light (A and B) for 3 minutes and fourth impression was disinfected by exposing it to UV light (A and B) for 10 minutes. The colony was observed based on standard method and technique under binocular microscope and the growth in broth were observed based on their turbidity with the help of colorimeter. Result: The intergroup comparison was done by using ANOVA test while the comparison between two groups was done by using paired t test. Conclusion: In this study sodium hypochlorite was found to be more effective in killing microorganisms than UV rays as it kills only surfaces microbes.
